Recently, I discovered that Synology has launched C2 Object Storage service, which is similar to Alibaba Cloud OSS and Tencent COS. It is also compatible with the S3 API. Currently, you can get 15GB of free storage after registration. If you're interested, you can give it a try.

Registering a Synology Account

• C2 Object Storage homepage: https://c2.synology.com/zh-tw/object-storage/overview

Click on the "Login" button in the upper right corner or the "Get 15GB" button on the homepage to be redirected to the registration page. If you already have an account, you can log in directly. If you don't have an account, you can register a new one. However, please note:

1. If you select Mainland China as the region, you won't be able to use C2 Object Storage. It is recommended to choose another region.
2. It seems that the official website verifies whether the IP and selected region match. For example, if xiaoz is using a Hong Kong IP, selecting the Hong Kong region for registration should be fine.

Pricing

After registration, you will get 15GB of free storage and 15GB of free traffic (until September 30, 2022, all download traffic will not incur additional charges). However, please note that if you choose a paid plan later, the amount of downloaded traffic will be equal to the amount of storage. For example, if you have 1TB of storage, you will have 1TB of downloaded traffic. In other words, the storage and downloaded traffic have a 1:1 ratio, which is similar to Wasabi's traffic rules. Personally, I don't really like this billing method.

Currently, C2 Object Storage has three regions: Taiwan, the United States, and Europe.

The prices vary for different regions. Below are the prices for each region, as compiled by xiaoz:

• Taiwan: $10.99/1TB/month
• United States: $6.99/1TB/month
• Europe: €6.99/1TB/month

Overall, these prices are relatively cheap.

Additional Notes

• The functionality of C2 Object Storage is currently very basic, so it is not recommended for production use at the moment.
• I couldn't find any place in the backend where bucket permissions can be set.
• I haven't found the official documentation for C2 Object Storage yet.

Personally, I would recommend B2 Object Storage, which offers 10GB of free storage with pay-as-you-go pricing and can also be integrated with CloudFlare to reduce traffic costs. The storage fees are also very affordable. Check it out here: https://blog.xiaoz.org/archives/13256
